Fernando Alonso says he has lost "about 60" points due to mechanical issues across the Formula One season, describing Alpine's problems as "unacceptable" after retiring from the Singapore Grand Prix.

Alpine suffered their first double retirement of the 2022 campaign on Sunday, as suspected power unit issues ended the races of Alonso and team-mate Esteban Ocon.

Alonso was defending sixth place against the advances of Max Verstappen when the problem first struck, forcing him out of the race after 21 laps. Ocon, meanwhile, followed six laps later.

The issue overshadowed a landmark day for Alonso, who made a record 351st grand prix start, and the Spaniard made his frustration known after the race.

"Again eight or 10 points are gone and there were already about 50 points lost this year," Alonso said. "So there are already about 60, which is unacceptable.

"I am very upset because there had been a good performance in this race on my part throughout the weekend.

"Yes, it was the two [Alpine] cars, but one was behind and out of the points, and it was not as serious as in my case for the points.

"This year, this changes everything. If you gave me 60 more points in the standings and reduced those of the rest – because they are points that the others would not have added – my championship would seem much better, even compared to Mercedes."

Alonso has retired from four of his 17 races in 2022, including back-to-back outings at Monza and Singapore. 

The two-time world champion, who is set to replace the retiring Sebastian Vettel at Aston Martin next year, sits ninth in the drivers' championship standings, seven points behind team-mate Ocon.

Lewis Hamilton hopes he can belatedly celebrate his first win of 2022 at the Singapore Grand Prix, believing such a result would pay back Mercedes and his fans for their support in a difficult year.

Hamilton is facing the first winless season of his Formula One career after falling out of title contention.

The seven-time world champion has made six podiums this year but is still waiting to return to the top step with only six races remaining in the season.

Hamilton at least appears to have the pace in Singapore, where he qualified third-fastest on Saturday and revealed only "an oversteer moment" at Turn 16 denied him the chance to take pole ahead of Charles Leclerc.

It was still the Briton's best qualifying performance of the season – which came as a surprise to him – and he is looking to improve further on race day.

"It feels incredibly rewarding, I think, for everyone in the team [to get this performance]," Hamilton said in a press conference.

"We've really started with a real handful, a difficult deck of cards that we've created for ourselves, and [it has meant] reshuffling and lots and lots of work.

"Everyone [has been] staying really positive, or as positive as possible, and everyone is just being incredibly diligent and never giving up.

"So, it's been an inspiring year for me, witnessing what my team do and being a part of that, and yeah, I so badly want to [win].

"Naturally the will and desire to get a good result for them, to pay them back for all their great work is part of it.

"Also, my fans have been the most incredible this year, on and off track. And we couldn't have survived the year without them. So, I also want it for them.

"But I think we've got a great turnout here this weekend. And I hope that tomorrow we can give them a good show."

This weekend, in which Max Verstappen can clinch a second straight title, albeit the Dutchman's chances have been reduced by a frustrating qualifying session, has been overshadowed by speculation of a major salary cap breach.

Red Bull, Verstappen's team, have been forced to deny claims they are the guilty party, and Hamilton was not interested in engaging in gossip.

"I'm not really giving it much attention, to be honest," he said. "It's all whispers at the moment.

"I don't know enough about it to be able to make a sensible comment. I'm not thinking particularly anything.

"I'm proud of my team for the diligence that they've done to run to the rules.

"And honestly, I have full confidence in Mohammed [bin Sulayem, FIA president] in the way that he's conducted himself to this point and in terms of being strict and being clear with the rules.

"The rules are rules, and for those sort of things, which can lead to real alterations in terms of car performance, those sorts of things, we definitely have to take it seriously.

"But as I said, I don't know if it's true or not, so we'll see."

Max Verstappen was forced to abandon his final lap in qualifying after his Red Bull ran out of fuel in Singapore, he confirmed after the session.

The reigning Formula One world champion was pushing to leapfrog Ferrari's Charles Leclerc for pole position in a wet session under the lights but was called into the pits as he approached the line.

Verstappen immediately expressed his fury over team radio and subsequently confirmed in the media pen that he was called in because there was not enough fuel left in the car.

"They told me to abort so I thought okay I'll do that but then on the final lap, they told me to box and then I realised what was going to happen and we ran out of fuel," he told Sky Sports.

"That's just incredibly frustrating and shouldn't happen. And even when you under-fuel it, you track that throughout the session, you're not going to make it and we should've seen that clearly.

"Not happy at the moment. It's a team effort. I can make mistakes and the team can make mistakes but it's never acceptable. Of course, you learn from it but this is really bad and  shouldn't happen."

F1 regulations state that each team must have enough fuel remaining after qualifying for scrutineering, with punishments issued if the required amount cannot be met.

Verstappen will start eighth on the grid for Sunday's race in south east Asia, where he can mathematically win the title but would require a massive shake-up across the grid.

George Russell has described Alex Albon's decision to return for the Singapore Grand Prix as "audacious", praising the Williams driver's determination to feature in what he feels is Formula One's "toughest race".

Albon spent a night in intensive care earlier in September after suffering respiratory failure following treatment for appendicitis.

The 26-year-old was then replaced by Nyck de Vries for the Italian Grand Prix, but is set to return to the grid this weekend.

The Singapore race is the longest of the F1 season, while the humid conditions at the Marina Bay Street Circuit are expected to test drivers' stamina. 

Russell – whose move to Mercedes paved the way for Albon to assume his seat with Williams – has been impressed by his recovery, saying: "It's definitely audacious to come back for the toughest race of the season having only just recovered.

"But it just goes to show the sort of grit and determination he has. I was in contact with his family on the Saturday night because it was looking very scary at one point.

"But it's pretty impressive to see how he recovered so quickly. The human body is a scary thing.

"It just goes to show one minute everything is fine, and the next minute everything can change almost totally out of your control. It will be interesting to see how he gets on this weekend."

Asked about the difficult conditions drivers will face this weekend, Russell added: "It doesn't matter how much training you do, you will never be able to replicate what you go through on track.

"I have been training with at least three layers of clothes on every single gym session, every time I go out on the bike.

"It's pretty uncomfortable. It's quite impressive how difficult the body handles heat, even in the sauna for half an hour. That's what we will be experiencing in the car. And then there is the physical element and cognitive side of things."

Max Verstappen suggested he would have liked to see Ferrari take the Formula One title fight to the wire ahead of his first opportunity to seal consecutive championships.

Verstappen could retain the drivers' championship at Sunday's Singapore Grand Prix, although it appears an unlikely prospect as he requires both Sergio Perez and Charles Leclerc to post poor finishes.

Nevertheless, it appears to be a matter of time before Verstappen clinches his second crown, with Ferrari's issues with reliability and strategy costing Leclerc the chance to compete.

Verstappen holds a 119-point lead over Leclerc at the top of the standings after winning each of the last five races, and the Dutchman says he would have relished a closer battle.

"I mean, [there are] two sides. Yes, in one way, I would have liked them to still be in the fight," he said on Thursday. 

"But from my side, of course it's also nice to win it in a more calm way. 

"I think what is good to see is that they are very competitive this year compared to the last few years, and I think that's what F1 needed."

Meanwhile, Verstappen is not getting carried away by the prospect of wrapping up the title in Singapore, and has revealed he would prefer to seal the deal at next week's Japanese Grand Prix.

"It's a bit unrealistic for it to happen. So I don't really think about it," Verstappen added. "It's quite a long shot. I just want to enjoy the weekend, and of course, try to win it.

"I think Japan is nicer. I'm really excited to go back there, It's been a while. It's an amazing track and for me, anyway, it has quite special memories.

"The first time I drove an F1 car was there in FP1, and I will always remember that. And besides that, it is kind of a home GP with [Red Bull engine provider] Honda.

"I think [it will be] my first proper opportunity to win the title. So yeah, of course, I'm looking forward to Singapore right now. But I'm also very excited for next weekend."

Lewis Hamilton has declared he "feels for the fans" after Max Verstappen's dominance of the F1 championship battle this season.

The Red Bull ace tops the standings by a whopping 116 points heading into Sunday's race at Singapore, where he can clinch the crown if a series of permutations are met.

It is unlikely that Singapore will be the race where Verstappen wins the title, with a more likely scenario seeing him crowned champion the following week in Japan.

Either way, a second title in a row for Verstappen is inevitable and Hamilton has declared it is "never great" when the battle is concluded prematurely.

"I definitely feel for the fans because for everyone and even for us, last year, going right down to the wire, that was intense for everybody. So, it's never great when the season finishes early," he said at a news conference on Thursday.

"Even when I've experienced having it finish early in places like Mexico. For you as the one individual, it's great but for the actual sport it's not spectacular.

"I'm really grateful to have had 2008 right down to the last 17 seconds, and obviously last year, pretty much the same thing. Let's hope for the future, it's a bit better."

Williams have confirmed that Alex Albon will be back behind the wheel at this week's Singapore Grand Prix after recovering from appendicitis.

Albon spent a night in intensive care earlier this month after suffering respiratory failure due to post-operative anaesthetic complications, forcing him to miss the Italian Grand Prix.

The 26-year-old was replaced by Formula One debutant Nyck de Vries, who finished ninth at Monza.

Albon is now targeting a return to action in Singapore, but he is aware of just how tough it will be to ease himself back in on one of the calendar's most demanding tracks.

"Firstly, I'd just like to thank everyone for all their messages and support over the Italian Grand Prix weekend," he said in a statement released on Wednesday.

"My preparation has been a little different than normal but I'm feeling good and I've done everything possible to get ready for one of the most physical races on the calendar.

"I am not underestimating how big of a challenge this is going to be, but I am looking forward to hitting the track on Friday and getting back driving.

"It's a great street circuit and the closest race to home for me in Thailand, so I'm really excited to be here and to see the fans that have turned out."

Albon is 19th in the drivers' championship with four points after 16 races.

De Vries is on two points from one race, while fellow Williams driver Nicholas Latifi – who is leaving at the end of the campaign – is without a point.

Williams driver Alex Albon suffered complications following surgery for appendicitis that led to respiratory failure and intensive care, but he is expected to return home on Tuesday.

It was announced on Saturday that Albon would not race in the Italian Grand Prix at Monza having been transferred to hospital, with Nyck de Vries deputising in his place and finishing ninth to secure points in his first ever F1 race.

Albon is expected to return to for the next round of racing in Singapore, but a statement issued by Williams on Monday detailed complications that arose after the 26-year-old's surgery.

"Further to Alex Albon's diagnosis of appendicitis on the morning of Saturday 10 September, he was admitted to San Gerardo hospital for treatment. He underwent a successful laparoscopic surgery on Saturday lunchtime," the statement said.

"Following surgery, Alex suffered with unexpected post-operative anaesthetic complications which led to respiratory failure, a known but uncommon complication. He was re-intubated and transferred to intensive care for support.

"He made excellent progress overnight and was able to be removed from mechanical ventilation yesterday morning. He has now been transferred to a general ward and is expected to return home tomorrow. There were no other complications.

"Alex's full focus is on recovery and preparation ahead of the Singapore Grand Prix later this month."

The Singapore Grand Prix will be on the Formula One calendar until at least 2028 after a seven-year contract extension to stage the race was agreed.

There was no racing at the Marina Bay Street Circuit in the past two seasons due to the coronavirus pandemic, but the 2022 race is set to go ahead on October 2.

F1 on Thursday announced that a deal has been agreed with Singapore GP Pte Ltd (SGP) and the Singapore Tourism Board (STB) for the event to remain on the calendar for at least another seven seasons.

"I am delighted that Formula One will continue to race in Singapore for another seven years," said F1 president and CEO Stefano Domenicali.

"The Marina Bay Street Circuit hosted the first night race in F1 history in 2008, and Singapore has continued to thrill fans, teams, and drivers ever since. Singapore holds a special place on the F1 calendar, and this extension is part of our long-term commitment to continue to grow the sport in Asia.

"The plans that are in place to reduce the carbon footprint of the event are impressive and align with our plans to be Net Zero Carbon as a sport by 2030 and I look forward to continuing our successful relationship with Singapore GP and the Singapore Tourism Board as Formula One returns to this incredible city."

Singapore GP's chairman Mr Ong Beng Seng said: "We are very pleased that the night race will continue for seven more years.

"After more than a decade of celebrating this spectacular event on the racing calendar, we are looking forward to building on its success and working with Formula One as well as its partners to take the night race to greater heights. We are delighted that this marquee event will demonstrate how Singapore is open for business.

"We look forward to welcoming both local and overseas fans and visitors to the Marina Bay Street Circuit once again."

The Singapore Grand Prix is cancelled and "several options" for alternative races are being considered, Formula One organisers have confirmed.

The race at the Marina Bay Street Circuit was originally scheduled for October 1-3 this year.

However, the event has been called off amid concerns from authorities that Singapore's strict coronavirus control measures would not be compatible with thousands entering the country for the weekend.

A statement from F1 on Friday said: "Formula One and race organisers have confirmed that this year's Singapore Grand Prix will not take place, with organisers citing ongoing safety and logistic concerns brought about by the Covid-19 pandemic.

"As previously stated, Formula One say they will continue to work with all promoters during this fluid time and have several options for additional races."

Colin Syn, deputy chairman of the race, was quoted by the BBC as saying that cancelling the Singapore event for the second year running was "an incredibly difficult decision" but necessary due to "the prevailing restrictions for live events in Singapore".

The city state has tough measures in place to limit travel from abroad, while a robust test-and-trace system has helped to keep COVID-19 cases to just over 62,000.

According to reports, Turkey is being considered as an alternative venue. Istanbul Park was due to be used as a substitute for the Canadian Grand Prix but was cancelled after a rise in coronavirus cases.

A revival of the postponed Chinese Grand Prix and a possible second race in Austin, Texas have also been mooted.
